Doughnut frying apparatus has a conveyor extending lengthwise of the hot oil tank and provided with transverse flights with its upper course disposed to carry floating doughnuts from a transverse pickup zone near the infeed or rear end of the tank towards the outfeed end thereof. Successive series of uncooked doughnuts are delivered into the tank in a transverse receiving zone spaced rearwardly of the pickup zone. Means are employed to enable the interval between the delivery of successive series to be minimized by circulating hot oil to provide a stream flowing upwardly through the receiving zone and into the pickup zone preferably also with an air stream directed close to but above the surface of the oil and forwardly through the delivery zone.
